Question

Find the mean of the following numbers.

-2, 9, -10, 3, 5, 1


A. -6

B. -1

C. 1

D. 6

Answer 1

C - 1

Explanation:

The mean is the sum total of all the given value within the data set divided by the number of values in the data set. By counting, you can find that we have 6 values in our data set.

First thing you need to do is add all the numbers given together in order to get the sum of the values in the given data set. Follow these steps presented below:

-2 + 9 - 10 + 3 + 5 + 1

7 - 10 + 3 + 5 + 1

- 3 + 3 + 5 + 1

0 + 5 + 1

5 + 1

6

Now, in order to find the mean, take the sum (6) and divide by the amount of numbers there are; 6.

6/6 = 1

Therefore, the mean is 1.

Hope this helps!
